（固着具）
本実施形態において、固着具１は、図１に示すように、ねじ２と、２つのワッシャ３とを含んでいる。ねじ２は、頭部２ａと、ねじ部２ｂとを含む。頭部２ａのねじ部２ｂとは反対側の面には、ねじ締め工具５が嵌合される六角形状の嵌合孔２ｃが形成されている。ねじ部２ｂは、頭部２ａから垂直に延出され、外周面にねじ山が形成されている。各ワッシャ３は、ねじ部２ｂに挿通される。 (Fixing tool)
In this embodiment, the fastener 1 includes a screw 2 and two washers 3, as shown in FIG. The screw 2 includes a head portion 2a and a screw portion 2b. A hexagonal fitting hole 2c into which the screw tightening tool 5 is fitted is formed on the surface of the head portion 2a opposite to the screw portion 2b. The threaded portion 2b extends vertically from the head portion 2a, and a thread is formed on the outer peripheral surface. Each washer 3 is inserted through the threaded portion 2b.

（ねじ締め工具）
本実施形態において、ねじ締め工具５は、図１に示すように、六角レンチ（六角棒レンチ、六角棒スパナ）である。ねじ締め工具５は、一端側にねじ部２ｂの嵌合孔２ｃに嵌合される嵌合部５ａが形成され、嵌合部５ａから他端側に向けて一軸に延びる軸状部５ｂが形成されている。嵌合部５ａは、六角形状に形成される。また、ねじ締め工具５の他端すなわち軸状部５ｂの嵌合部５ａとは反対側の端部は、軸状部５ｂが折り曲げられた把持部５ｃが形成されている。把持部５ｃは、作業者がねじ締め工具５を回転させる際に把持する部分である。なお、ねじ締め工具５は、六角レンチに限られない。ねじ締め工具５は、例えば、ドライバーであってもよい。その場合、ドライバーの先端が嵌合部であり、先端まで一軸に延びる部分が軸状部であり、軸状部の端部に設けられた作業者が把持する部分が把持部となる。つまり、ねじ締め工具５は、一軸に延在する軸状部分の先端にねじ２と嵌合する部分を有し、回転によりねじ２を締め付けることができる工具であればよい。 (Screw tightening tool)
In the present embodiment, the screw tightening tool 5 is a hexagon wrench (hexagon bar wrench, hexagon bar spanner) as shown in FIG. In the screw tightening tool 5, a fitting portion 5a that is fitted into the fitting hole 2c of the screw portion 2b is formed on one end side, and a shaft-shaped portion 5b that extends uniaxially from the fitting portion 5a toward the other end side is formed. Has been done. The fitting portion 5a is formed in a hexagonal shape. Further, a grip portion 5c in which the shaft-shaped portion 5b is bent is formed at the other end of the screw tightening tool 5, that is, the end portion of the shaft-shaped portion 5b opposite to the fitting portion 5a. The grip portion 5c is a portion to be gripped when the operator rotates the screw tightening tool 5. The screw tightening tool 5 is not limited to the hexagon wrench. The screw tightening tool 5 may be, for example, a screwdriver. In that case, the tip of the driver is the fitting portion, the portion extending uniaxially to the tip is the shaft-shaped portion, and the portion gripped by the operator provided at the end of the shaft-shaped portion is the gripping portion. That is, the screw tightening tool 5 may be any tool that has a portion that fits with the screw 2 at the tip of the shaft-shaped portion extending uniaxially and can tighten the screw 2 by rotation.

（ねじ止め治具）
ねじ止め治具１００は、図１から図３に示すように、ねじ締め工具保持部１０と、ねじ保持部２０とを備える。 (Screw fixing jig)
As shown in FIGS. 1 to 3, the screw fixing jig 100 includes a screw tightening tool holding portion 10 and a screw holding portion 20.

（ねじ締め工具保持部）
ねじ締め工具保持部１０は、ねじ締め工具５の長手方向に沿って延在し、ねじ締め工具５を保持する。ねじ締め工具５の長手方向とは、軸状部５ｂの延在方向である。ねじ締め工具５の長手方向に沿って延在するとは、ねじ締め工具保持部１０にねじ締め工具５を保持させた状態で、ねじ締め工具５の軸状部５ｂと同方向に延在することを意味する。言い換えると、ねじ締め工具保持部１０は、軸状部５ｂと同様に、一軸に延びる。本実施形態において、ねじ締め工具保持部１０は、ねじ締め工具５の軸状部５ｂよりも短い長さで一軸に延びる円筒状部である。以下の説明では、ねじ締め工具保持部１０の軸方向を単に「軸方向」と称し、ねじ締め工具保持部１０の径方向を単に「径方向」と称する。 (Screw tightening tool holding part)
The screw tightening tool holding portion 10 extends along the longitudinal direction of the screw tightening tool 5 and holds the screw tightening tool 5. The longitudinal direction of the screw tightening tool 5 is the extending direction of the shaft-shaped portion 5b. Extending along the longitudinal direction of the screw tightening tool 5 means extending in the same direction as the shaft-shaped portion 5b of the screw tightening tool 5 while the screw tightening tool 5 is held by the screw tightening tool holding portion 10. Means. In other words, the screw tightening tool holding portion 10 extends uniaxially like the shaft-shaped portion 5b. In the present embodiment, the screw tightening tool holding portion 10 is a cylindrical portion extending uniaxially with a length shorter than the shaft-shaped portion 5b of the screw tightening tool 5. In the following description, the axial direction of the screw tightening tool holding portion 10 is simply referred to as "axial direction", and the radial direction of the screw tightening tool holding portion 10 is simply referred to as "diameter direction".

ねじ締め工具保持部１０は、その内部に、軸方向における一端１０ａから他端１０ｂまでを貫通する貫通孔１５が形成されている。貫通孔１５は、軸状部５ｂよりわずかに大きな径で形成されており、図２に示すように、軸状部５ｂを回転自在に収容する。これにより、ねじ締め工具保持部１０は、図１に破線矢印で示すように、他端１０ｂ側から貫通孔１５に挿入されたねじ締め工具５を回転自在に保持することができる。このとき、図２に示すように、嵌合部５ａは、一端１０ａ側で貫通孔１５から突出する位置に位置づけられる。なお、ねじ締め工具保持部１０は、ねじ締め工具５の長手方向に沿って延在し、軸状部５ｂを回転自在に保持することができれば、径方向断面において一部が切り欠かれた形状（例えばＵ字形状、Ｃ字形状等）に形成されてもよい。 The screw tightening tool holding portion 10 is formed with a through hole 15 that penetrates from one end 10a to the other end 10b in the axial direction. The through hole 15 is formed with a diameter slightly larger than that of the shaft-shaped portion 5b, and as shown in FIG. 2, the shaft-shaped portion 5b is rotatably accommodated. As a result, the screw tightening tool holding portion 10 can rotatably hold the screw tightening tool 5 inserted into the through hole 15 from the other end 10b side as shown by the broken line arrow in FIG. At this time, as shown in FIG. 2, the fitting portion 5a is positioned at one end 10a side so as to protrude from the through hole 15. The screw tightening tool holding portion 10 extends along the longitudinal direction of the screw tightening tool 5, and if the shaft-shaped portion 5b can be rotatably held, the shape is partially cut out in the radial cross section. It may be formed (for example, U-shaped, C-shaped, etc.).

（ねじ保持部）
ねじ保持部２０は、ねじ締め工具保持部１０の下方で、ねじ締め工具保持部１０と連結され、ねじ２を保持する。ねじ保持部２０は、ねじ締め工具保持部１０のねじ締め工具５が挿入される他端１０ｂとは反対側の一端１０ａにおいて、ねじ締め工具保持部１０の外縁に設けられている。なお、ねじ締め工具保持部１０の下方で連結されるとは、ねじ締め工具保持部１０の一端１０ａを鉛直方向の下向きに位置づけたときに、ねじ保持部２０がねじ締め工具保持部１０に対して下方に位置することを意味する。ねじ保持部２０は、図１から図３に示すように、連結部２１と、底部２２と、切り欠け２３とを有している。 (Screw holder)
The screw holding portion 20 is connected to the screw tightening tool holding portion 10 below the screw tightening tool holding portion 10 to hold the screw 2. The screw holding portion 20 is provided on the outer edge of the screw tightening tool holding portion 10 at one end 10a on the side opposite to the other end 10b into which the screw tightening tool 5 of the screw tightening tool holding portion 10 is inserted. Note that the connection is made below the screw tightening tool holding portion 10 means that when one end 10a of the screw tightening tool holding portion 10 is positioned downward in the vertical direction, the screw holding portion 20 is connected to the screw tightening tool holding portion 10. It means that it is located below. As shown in FIGS. 1 to 3, the screw holding portion 20 has a connecting portion 21, a bottom portion 22, and a notch 23.

連結部２１は、ねじ締め工具保持部１０の一端１０ａにおける外縁から軸方向に平板状に延びる。なお、連結部２１は、少なくとも軸方向に延びる部分を有するものであればよく、強度を確保することができれば、平板状に限らず棒状等であってもよい。底部２２は、連結部２１のねじ締め工具保持部１０とは反対側の端部から径方向に向けて垂直に立ち上がり、ねじ締め工具保持部１０の一端１０ａ側の面と対向する。底部２２のねじ締め工具保持部１０側の面は、ワッシャ３を介してねじ２を載置する載置面２２ａとなる。 The connecting portion 21 extends axially from the outer edge of one end 10a of the screw tightening tool holding portion 10 in a flat plate shape. The connecting portion 21 may have at least a portion extending in the axial direction, and may have a rod shape or the like as long as the strength can be secured. The bottom portion 22 rises vertically in the radial direction from the end portion of the connecting portion 21 opposite to the screw tightening tool holding portion 10, and faces the surface of the screw tightening tool holding portion 10 on the one end 10a side. The surface of the bottom portion 22 on the screw tightening tool holding portion 10 side becomes a mounting surface 22a on which the screw 2 is mounted via the washer 3.

切り欠け２３は、図１から図３に示すように、載置面２２ａの外縁から中心（ねじ締め工具保持部１０の軸中心）に向かう方向に延びる溝状部である。言い換えると、切り欠け２３は、底部２２の連結部２１と反対側の端部から、連結部２１側に向けて溝状に延びる。切り欠け２３は、軸方向からみて、貫通孔１５と重なる位置に形成される。切り欠け２３には、図２および図３に示すように、ねじ部２ｂが挿入される。そのため、切り欠け２３は、少なくともねじ部２ｂが回転自在かつ摺動自在となる溝幅で形成される。また、切り欠け２３は、図３に示すように、ねじ２の軸中心とねじ締め工具保持部１０の軸中心とを同軸上に並べることができる溝深さに形成される。なお、ねじ部２ｂが切り欠け２３の終端に当接した状態で、ねじ２の軸中心とねじ締め工具保持部１０の軸中心とが同軸上に並ぶことが好ましい。 As shown in FIGS. 1 to 3, the notch 23 is a groove-shaped portion extending in a direction extending from the outer edge of the mounting surface 22a toward the center (the axial center of the screw tightening tool holding portion 10). In other words, the notch 23 extends in a groove shape from the end of the bottom portion 22 opposite to the connecting portion 21 toward the connecting portion 21 side. The notch 23 is formed at a position overlapping the through hole 15 when viewed from the axial direction. As shown in FIGS. 2 and 3, the threaded portion 2b is inserted into the notch 23. Therefore, the notch 23 is formed with a groove width at which at least the threaded portion 2b is rotatable and slidable. Further, as shown in FIG. 3, the notch 23 is formed at a groove depth at which the axial center of the screw 2 and the axial center of the screw tightening tool holding portion 10 can be aligned coaxially. It is preferable that the shaft center of the screw 2 and the shaft center of the screw tightening tool holding portion 10 are aligned coaxially with the screw portion 2b in contact with the end of the notch 23.

以上の構成により、切り欠け２３の縁にねじ２の頭部２ａがワッシャ３を介して保持される。すなわち、ねじ締め工具保持部１０の一端１０ａを鉛直方向の下向きに位置づけたとき、底部２２の載置面２２ａにねじ２の頭部２ａがワッシャ３を介して載置され、ねじ２のねじ部２ｂが切り欠き２３から軸方向において突出した状態となる。その結果、ねじ２がねじ保持部２０に安定的に保持される。 With the above configuration, the head portion 2a of the screw 2 is held by the edge of the notch 23 via the washer 3. That is, when one end 10a of the screw tightening tool holding portion 10 is positioned downward in the vertical direction, the head portion 2a of the screw 2 is mounted on the mounting surface 22a of the bottom portion 22 via the washer 3, and the screw portion of the screw 2 is mounted. 2b is in a state of protruding from the notch 23 in the axial direction. As a result, the screw 2 is stably held by the screw holding portion 20.

（ねじ止め作業）
次に、ねじ止め治具１００に固着具１およびねじ締め工具５を保持させて、ねじ止め作業を実施する動作について説明する。作業者は、図１の実線矢印に示すように、固着具１、すなわち、ねじ２およびワッシャ３をねじ保持部２０に保持させる。具体的には、ねじ部２ｂにワッシャ３を挿入した状態で、ねじ部２ｂをねじ保持部２０の切り欠け２３に挿入する。このとき、底部２２の載置面２２ａにねじ２およびワッシャ３を載置し、頭部２ａを切り欠け２３の縁で保持させることができるため、作業者は、固着具１を容易に取り扱うことができる。なお、実施形態において、切り欠け２３がねじ２の頭部２ａを保持できる溝幅であれば、ワッシャ３は、必須ではない。すなわち、切り欠け２３の溝幅が頭部２ａの外径よりも小さく、頭部２ａを載置面２２ａに直接的に載置して、ねじ２をねじ保持部２０により安定的に保持することができれば、ワッシャ３は、省略されてもよい。 (Screw fastening work)
Next, an operation of holding the fixing tool 1 and the screw tightening tool 5 on the screwing jig 100 and performing the screwing operation will be described. As shown by the solid arrow in FIG. 1, the operator causes the fixing tool 1, that is, the screw 2 and the washer 3 to be held by the screw holding portion 20. Specifically, with the washer 3 inserted in the screw portion 2b, the screw portion 2b is inserted into the notch 23 of the screw holding portion 20. At this time, since the screw 2 and the washer 3 can be placed on the mounting surface 22a of the bottom portion 22 and the head portion 2a can be held by the edge of the notch 23, the operator can easily handle the fastener 1. Can be done. In the embodiment, the washer 3 is not essential as long as the notch 23 has a groove width capable of holding the head portion 2a of the screw 2. That is, the groove width of the notch 23 is smaller than the outer diameter of the head 2a, the head 2a is placed directly on the mounting surface 22a, and the screw 2 is stably held by the screw holding portion 20. If possible, the washer 3 may be omitted.

また、作業者は、図１の破線矢印に示すように、ねじ締め工具５をねじ締め工具保持部１０の他端１０ｂ側から貫通孔１５に挿入し、一端１０ａ側に嵌合部５ａを突出させる。ねじ保持部２０に保持されたねじ２の頭部２ａに形成された嵌合孔２ｃと、ねじ締め工具５の嵌合部５ａとが互いに向かいあう方向をとるため、作業者は、嵌合孔２ｃに嵌合部５ａを容易に嵌めあわせることができる。これにより、図２に示すように、固着具１およびねじ締め工具５が互いに嵌合し、同軸上に回転自在な状態で、ねじ止め治具１００により保持される。 Further, as shown by the broken line arrow in FIG. 1, the operator inserts the screw tightening tool 5 into the through hole 15 from the other end 10b side of the screw tightening tool holding portion 10, and the fitting portion 5a protrudes to one end 10a side. Let me. Since the fitting hole 2c formed in the head portion 2a of the screw 2 held by the screw holding portion 20 and the fitting portion 5a of the screw tightening tool 5 face each other, the operator can perform the fitting hole 2c. The fitting portion 5a can be easily fitted into the fitting portion 5a. As a result, as shown in FIG. 2, the fixing tool 1 and the screw tightening tool 5 are fitted to each other and held by the screw fixing jig 100 in a coaxially rotatable state.

作業者は、固着具１およびねじ締め工具５を保持させたねじ止め治具１００を図示しない所定箇所に位置付ける。すなわち、ねじ部２ｂを図示しないねじ孔に挿入し、ねじ締め工具５の把持部５ｃを把持してねじ締め工具５を回転させることで、ねじ２を所定箇所に仮締めする。このとき、ねじ止め治具１００が軸状に延びる部材であることから、狭い箇所にも挿入しやすく、かつ、ねじ２がねじ保持部２０で保持されているため、ねじ２の脱落が抑制される。ねじ２の仮締めが完了すると、作業者は、ねじ締め工具５を軸方向に引っ張ることで、ねじ２とねじ締め工具５との嵌合を解除する。さらに、作業者は、仮締めされたねじ２に対して、ねじ止め治具１００を径方向にスライドさせることで、切り欠け２３からねじ部２ｂを離脱させる。これにより、ねじ止め治具１００とねじ２（固着具１）とが分離される。最後に、作業者は、ねじ止め治具１００から取り外したねじ締め工具５を用いて、仮締めされたねじ２を本締めする。 The operator positions the screw fixing jig 100 holding the fixing tool 1 and the screw tightening tool 5 at a predetermined position (not shown). That is, the screw 2b is temporarily tightened at a predetermined position by inserting the screw portion 2b into a screw hole (not shown), gripping the grip portion 5c of the screw tightening tool 5 and rotating the screw tightening tool 5. At this time, since the screw fixing jig 100 is a member extending in a shaft shape, it is easy to insert it into a narrow place, and since the screw 2 is held by the screw holding portion 20, the screw 2 is suppressed from falling off. To. When the temporary tightening of the screw 2 is completed, the operator pulls the screw tightening tool 5 in the axial direction to release the fitting between the screw 2 and the screw tightening tool 5. Further, the operator slides the screw fixing jig 100 in the radial direction with respect to the temporarily tightened screw 2 to separate the screw portion 2b from the notch 23. As a result, the screw fixing jig 100 and the screw 2 (fixing tool 1) are separated. Finally, the operator finally tightens the temporarily tightened screw 2 by using the screw tightening tool 5 removed from the screw fixing jig 100.

（実施形態の作用効果）
以上説明したように、実施形態にかかるねじ止め治具１００は、ねじ締め工具５の長手方向に沿って延在しねじ締め工具５を保持するねじ締め工具保持部１０と、ねじ締め工具保持部１０の下方でねじ締め工具保持部１０と連結されねじ２を保持するねじ保持部２０と、を備える。 (Action and effect of the embodiment)
As described above, the screw tightening jig 100 according to the embodiment includes a screw tightening tool holding portion 10 extending along the longitudinal direction of the screw tightening tool 5 to hold the screw tightening tool 5, and a screw tightening tool holding portion. A screw holding portion 20 that is connected to the screw tightening tool holding portion 10 and holds the screw 2 below the 10 is provided.

この構成により、ねじ締め工具保持部１０でねじ締め工具５を保持し、かつ、ねじ締め工具保持部１０に連結されたねじ保持部２０でねじ２を保持することができる。したがって、作業しづらい狭い箇所において、ねじの落下を抑制し、ねじ止め作業を容易にすることが可能となる。 With this configuration, the screw tightening tool 5 can be held by the screw tightening tool holding portion 10, and the screw 2 can be held by the screw holding portion 20 connected to the screw tightening tool holding portion 10. Therefore, it is possible to suppress the fall of the screw and facilitate the screwing work in a narrow place where the work is difficult.
